[0014] The present invention provides a hub polishing and grinding automation system, which has the following beneficial effects: 1. The wheel hub polishing and grinding automation system can fix the wheel hub to be polished and ground on the wheel hub mounting plate through the arrangement of the first screw rod, the first set block, the first motor, the long shaft, the wheel hub mounting plate and the fixing bolts, and move the wheel hub to different processing areas for processing according to needs. Through the arrangement of the first multi-section hydraulic telescopic rod, the mounting box, the polishing and grinding box, the polishing and grinding particles, the splash plate, the rotating groove, the mounting ear, the mounting shaft and the torsion spring, the polishing and grinding box can be driven to rise through the first multi-section hydraulic telescopic rod, so that the fixed wheel hub is immersed in the polishing and grinding particles, and then the wheel hub can be driven to rotate through the first motor to cooperate with the polishing and grinding particles to realize automatic polishing and grinding. The splash guard at the rear of the polishing box will cover the top of the polishing box through the elastic reset of the torsion spring, thereby preventing the polishing particles from splashing out of the wheel during polishing. Through the arrangement of the rotating shaft, the stirring rod, the first gear, the mounting frame and the rack, when the first multi-section hydraulic telescopic rod drives the mounting box and the polishing box to rise and fall, the first gear will mesh with the rack to drive the rotating shaft and the stirring rod to rotate. The stirring rod stirs the polishing particles so that the debris polished off during polishing can fall into the collection box through the strainer for collection, thereby preventing the polishing particles from being mixed with too many iron filings and impurities that affect the polishing quality, thereby ensuring the polishing effect and pass rate of the wheel hub by the polishing particles.

[0015] 2. The wheel hub polishing and grinding automation system is provided with a second multi-section hydraulic telescopic rod, a water tank, an air cylinder, an ear plate, a piston rod, a piston plate, an air intake pipe, an air intake non-return valve, an air guide pipe and an air distribution plate. After the wheel hub is polished, the second multi-section hydraulic telescopic rod can drive the water tank to move upward so that the wheel hub fixed on the wheel hub mounting plate is immersed in the cleaning liquid in the water tank. The long shaft and the wheel hub are driven to rotate by the first motor to be cleaned. At the same time, when the water tank rises, the piston plate moves upward in the air cylinder and the outside air can be drawn into the air cylinder through the air intake pipe and the air intake non-return valve. When the wheel hub is cleaned, the second multi-section hydraulic telescopic rod drives the water tank to move downward and the piston plate moves downward. The air in the air cylinder can be introduced into the air distribution cavity through the air guide pipe and then sprayed out through a number of air nozzles, thereby quickly drying the residual water on the surface of the wheel hub, facilitating subsequent operations and avoiding water stains after the wheel hub is cleaned.

[0016] 3. The wheel hub polishing and grinding automation system, through the arrangement of the loading and unloading drive box, the second slide, the second motor, the second screw rod, the second set of blocks, the connecting rod, the wheel hub positioning tray, the wheel hub placement groove and the fastening bolt through hole, can send the wheel hub to be polished to the bottom of the wheel hub mounting plate for installation and fixation, and facilitate the removal of the polished and polished wheel hub from the wheel hub mounting plate, without the need to manually lift the wheel hub to a high altitude, and the operation is more convenient.
